Enum string comparison To compare a string with an enum, extend from thestrclass when declaring your enumeration class, e.g.class Color(str, Enum):. You will then be able to compare a string to an enum member using the equality operator==. How to compare a string with an Enum in Pyt...
| assertRegexpMatches(self, text, expected_regexp, msg=None) | Fail the test unless the text matches the regular expression. | | assertSequenceEqual(self, seq1, seq2, msg=None, seq_type=None) | An equality assertion for ordered sequences (like lists and tuples). | | For the purposes...
Introduction|简介 这份文档为主Python发行版中标准库的Python代码提供了编码规范。请参阅相关的信息性PEP,该PEP描述了Python C实现中的C代码的样式指南。 这份文档和PEP 257(文档字符串规范)改编自Guido的原始Python样式指南文章,并加入了Barry样式指南的一些内容[2]。 随着额外的约定的发现和语言本身的变化使过去的约...
For example, you can compare a number and a string for equality with the == operator. However, you’ll get False as a result: Python >>> 2 == "2" False The integer 2 isn’t equal to the string "2". Therefore, you get False as a result. You can also use the != operator...

Similarly, A_eq and b_eq refer to equality constraints. You can use bounds to provide the lower and upper bounds on the decision variables.You can use the parameter method to define the linear programming method that you want to use. There are three options:...

This means that all you Policies can be defined in regex syntax (but if no regex defined in Policy falls back to simple string equality test) - it gives you better flexibility compared to simple strings, but carries a burden of relatively slow performance. You can configure a LRU cache ...
